From deity "Description:"
The dark god Azakhar is described as a towering, muscular warrior clad in blood-spattered black plate armor and wielding a barbed greataxe. Chains run from his belt to collars around the necks of distraught slaves, and his face is concealed by a full plate helm ; it is said that the face of “True Fear” is concealed behind the helm ’s visor. Azakhar is the embodiment of fear, tyranny, and oppression. He is the god of war for the sake of conquest, and his clerics – the Bloodknights - serve his will by spreading evil and fear, abducting and selling slaves, and waging war throughout Ryh’ardha.
The Infernal Emperor resides in a large castle in the center of Dis. This citadel is known as Acherus and is similar in appearance to Azakhar’s earthly temples, though multiplied a thousandfold. Acherus is home to countless devils, fiendish mercenaries, and spirits of those who died in Azakhar’s service, and the unfortunate creatures who have been captured and enslaved to serve them and their unholy master.
